The invention belongs to the technical field of new energy automobiles, and relates to a vehicle battery self-heating control method, a vehicle battery self-heating control device, a vehicle battery self-heating system, an automobile and a computer readable storage medium. The vehicle battery self-heating control method comprises the following steps that a battery heating request is obtained; obtaining vehicle state information, wherein the vehicle state information comprises real-time battery temperature information and vehicle gear information of the vehicle; and when the vehicle state information meets the condition of entering the self-heating mode, entering the self-heating mode to control a cooling liquid system to transmit heat generated by a vehicle motor and a motor controller to a battery of the vehicle so as to heat the battery. Therefore, the heat generated by the motor controller and the motor internal resistor can be fully utilized to heat the battery, and the heating rate can be effectively improved; and the scheme is simple in logic and easy to realize, the cruising ability of the battery can be effectively improved, the noise generated in the battery heating process is reduced, and the driving experience is optimized.

    本发明属于新能源汽车技术领域,涉及一种车辆电池自加热控制方法、车辆电池自加热控制装置、车辆电池自加热系统、汽车和计算机可读存储介质。其中,车辆电池自加热控制方法包括如下步骤:获取电池加热请求;获取车辆状态信息,车辆状态信息包括车辆的实时电池温度信息、车辆档位信息;当车辆状态信息符合进入自加热模式的条件时,进入自加热模式,以控制冷却液系统将车辆电机与电机控制器产生的热量传输至车辆的电池,以对电池进行加热。因此,本发明能够充分利用电机控制器与电机内阻产生的热量给电池加热,能有效提高加热速率;且该方案逻辑简单、易于实现,能有效提高电池的续航能力,降低电池加热过程中产生的噪声,优化驾驶体验。
